575616 ÷ 78 
We want to figure out the number of times 575616 can be divided by 78.

Going ahead to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 78

Step 2:
When dividing 57 by 78, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 78

Going ahead to step 3:
The number 78 fits into 575 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 546 from 575 and we're left with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 78

Step 4:
When dividing 296 by 78, we get 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 234 from 296 leaves us with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 78

On to step 5:
621 divided by 78 is 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 737.0
Deduct 546 from 621 and we're left with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 78

Moving on to step 6:
756 divided by 78 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 7379.0
If we subtract 702 from 756, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 7379.6
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
When dividing 720 by 78, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 7379.69
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7379.692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 7379.6923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
78 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7379.6923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7379.692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 7379.6923076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
When dividing 720 by 78, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 7379.69230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 7379.69230769 with a remainder of 1.8e-08.
